I would suggest trying the LEM Swap List.
LEM Swap is Low End Mac's Google Group for buying and selling Mac OS/OS X computers and related goods. iPhones and iPods are considered "related goods", but iPod and iPhone accessories are not. This is a Mac swap list, not an iPhone or iPod one. PCs are expressly forbidden even if they are running OS X, as are most *nix boxen except for NeXT hardware. Palms and PDAs are acceptable as long as they can be used with Macs. Vintage Apple hardware (Apple II, Apple III, Lisa, and Newton) are allowed.

This link is to an archive so you can take a look at the treasures offered. Good luck. 🙂
